fix(plugin): copy lib/ directory alongside hook in session-start#1103
Merged
Conversation
session-start.py only copied the mode-detect hook to ~/.claude/hooks/ but not the lib/ directory containing hud_state.py. This caused the hook's HUD state update to silently fail (ImportError caught by bare except), leaving the TUI sidebar stuck on "idle" for all modes. - Extract _install_hook_with_lib() to handle hook + lib/ copy together - Use shutil.copytree with dirs_exist_ok=True for lib/ updates - Exclude __pycache__/*.pyc from copytree to avoid stale bytecode - Add 3 tests (normal copy, update existing, no lib/ graceful) Closes #1102
